To all lwhom t may concern.'

Be it known that I, JESSE E. MCBRIDE, a citizen of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in J apanning-Conveyers, of which the following is a specification, reference being had therem to the accompanying drawings.

This invention relates to conveyers and is shown and described particularly in connection with a japanning conveyer, although the invention is not necessarily limited to the use mentioned.

Among the objects of the invention are to provide a continuously advancing chain conveyer or the like which is capable of movement in transverse planes; and especially to so construct and arrange the parts that a single chain construction can be employed for said purpose. The invention also resides in the assembly and details of the jointed link of the chain and in the novel mounting and arrangement of the chain and its supporting mechanism.

In the drawings:

Figure 1 is a diagrammatic plan view of a conveyer system embodying my invention;

Fig. 2 is an end view of the construction shown in Fig. 1;

Fig. 3 is an enlarged fragmentary side elevation of the conveyer mechanism;

Fig. 4 is a cross-section on the line 4 4 of Fig. 35

Fig. 5 1s a perspective view of one of the link units.

Describing in detail the particular embodiment of my invention shown in the drawings, and referring first to the gen. eral arrangement of parts, A designates an endless chain conveyer which is supported on a track B. At one end this track is return-bent back on to itself so that the chain is compelled to weave back and forth over the sprocket wheels C, C', etc., one of-Which is utilized as a driving` sprocket. This portion of the conveyer track is located within the drying oven, while the opposite end of the track extends above the japanning tank D and has a portion E extending downwardly so that the articles hanging on the conveyer are brought down into the liquid in the japanning tank and again carried upward out of the liquid and continuously advanced toward the drying oven F.

From the above description of the general arrangement it will be apparent that the conveying mechanism must be so arranged that t is capable of not only turning about a horizontal pivot when passing around the sprockets C, C', etc., but must also be adapted fcr movement in a transverse direction, that is, when passing over the downwardly offset portion E of the track. In the present construction I have obtained this advantage by a novel arrangement of chain conveyer, the detail construction of which is shown in Figs. 3, 4 and 5. The chain proper is formed of a series of links G, G and G2, the latter of which is formed of two sections I-I and H pivotally connected together by a horizontal pivot H2. 'lhe construction of this link permits the chain to' turn downward when passing through the japanning tank, while the trans- -verse turning of the chain, that is, around its vertical pivots, is permitted by the pivots I and I which connect the sections H and H with the links G. Similar vertical pivots J are alsoemployed for connecting the links G with the adjacent links G.

For supporting the chain from the track and also for supporting the article to be conveyed, the link G is formed with oppositely-.extending arms or projections K and K', the former of which has a seat K2 for receiving the article to be japanned or otherwise treated, while the upper arm K terminates in a bearing portion L. ,Through said bearing portion there projects the axle M of the wheels M and M2, there Abeing preferably roller bearings or other suitable antifriction members N located between the axle and the bearing member. The wheels M and M2 run in a track M3, which track is supported from the ceiling by suitable hangers O. The track itself is preferably formed in inverted U-shape with inwardly offset retaining anges O and O2.

When the chain is passing over the depressed portion 'E of the track the necessary upward movement of the chain is permitted by the'horizontal pivots H2. By this novel arrangement of the hanger and chain it is possible to employ a single chain conveyer for continuously advancing articles through japanning or other operations where it is necessary to cause the conveyer 'to turn in both the vertical and horizontal planes. Various changes, however, in the details of construction and arrangements and combinations of parts can be made without de parting from the scope of my invention.

What I claim as my invention is:

l. The combination with a apanning tank and a drying oven, of an endless chain conveyer having vertical and horizontal pivots arranged to pass through said drying oven and over the japanning tank, and supports for said conveyer for causing the same to turn about the vertical pivots and to turn about the horizontal pivots so as to carry the article downward into the liquid in the japanning tank.

2. The combination with a japanning tank and a drying oven, of an endless chain conveyer having vertical and horizontal pivots arranged to pass through said drying oven and over the japanning tank, and supports forsaid'conveyer for causing the same to turn about the vertical pivots and to turn about the horizontal pivots so as to carry the article downward into the liquid in the japannin tank, said conveyer comprising a single c ain.

3. The combination with a japanning tank and a. drying oven, of an endless chain conveyer having vertical and horizontal pivots arranged to pass through said drying oven and over the japanning tank, and supports for said conveyer for 'causing the same to turn about the vertical pivots and to turn about the horizontal pivots so as to carry the article downward into the liquid in the japanning tank, said conveyer comprising a single chain made up of a lplurality of links connected by vertical and horizontal pivots.

In testimony whereof I aifX my signature.

JESSE E. MCBRIDE.
